How Precision CNC Machining Improves the Lifespan of Heavy Truck Suspension Components

Misaligned mounting holes and imprecise outer sleeve dimensions on aftermarket suspension parts cause difficult installation and accelerated housing wear.

Technical & Material Highlights:

• CNC Accuracy: Micron-level machining tolerances on inner shafts and outer steel sleeves.

• Hydraulic Assembly: Automated hydraulic pressing ensuring exact concentricity between metal and rubber.

• Custom Tooling: Hundreds of custom moulds produced monthly to support multi-brand catalog expansion.

Specification Tolerances:

• Shaft Concentricity: ±0.02mm.

• Outer Diameter Tolerances: Precision ground for press-fit stability.

• Surface Treatment: Anti-rust painting and phosphate conversion coating.
